CamelBak Racebak Review
Cons: Expensive, bounces around if running or mountain biking.
Our Analysis and Test Results
The jersey material is comfortable and fits well. We're not crazy about having the bladder and padding high on the back; it's not super comfortable on warmer days. A standard jersey with a bottle and cage seems more comfortable for road cyclists. Although there is padding between the bladder and your back, we still felt sweaty there on rides. It's not nearly as comfortable as a standard jersey.
We were surprised by how much this pack bounced around. That is likely so because all the weight is so high on your back. It is way too bouncy for running and even a little too jiggly for mountain bike riding.
Ease of Drinking
As with all CB packs, water delivery is very good, with high flow from minimal effort. One downside to this design is if you wear any clothing over it, which you probably will, you always have to keep your jacket or shirt unzipped a little if you want access to the bite valve. The alternative is to have the hose come out from your back and sit over your shoulder. But the result is an annoying bouncing of hose and valve around your face and on your shoulder, especially on uneven terrain.
Ease of Filling
This bladder was the most difficult to fill of those we tested. Pulling the bladder out isn't bad, but replacing it is a chore. Every time you fill it you have to remove the whole shirt and any layers on top of the shirt. You can fill the reservoir without removing it, but you will need to be very careful not to get your shirt wet.
This is by far the lightest "pack" we tested. Considering that the shirt replaces you need for a layer, the rig is essentially weightless except for the bladder. For people who think the CamelBak bladders have been become too heavy over time, this style bladder will be welcome. It is much lighter and more simple; more similar to the CamelBak reservoirs used a decade ago.
This is the only CamelBak pack in our tests that leaked. At first we thought it was defective, but then we realized it just needs careful and strenuous tightening after filling. Not a major issue, but something to keep in mind, and the closure mechanism is not as easy to use as with other CamelBak packs.
Ease of Cleaning
Unlike most CamelBak packs, the opening is narrow, so it is not as easy to get a brush inside for cleaning. Also, it is the only CamelBak bladder we tested without a quick-release for the hose.
There is essentially zero storage. You could shove an energy bar or two inside the shirt but it would then be hard to access them.
If you just wear this, without any layer on top, you definitely are making a statement. It only comes in white and is skin tight. If you wear it under a layer, you look a little like a hunchback.
Sizing is tricky. Our main testers most of the time we wear medium but sometimes wear a small. We got a size large in the RaceBak and it was almost too small! So go up a size when you order.
